Web1 day ago · Yes, the two strands of the DNA molecules are joined through hydrogen bonds. The purines always bond with pyrimidines, however, the number of bonds differs between the two types of base pairing. The adenine molecule forms a double bond with thymine while guanine forms a triple bond with cytosine. WebHydrogen bonding in DNA: DNA is made up of four bases Adenine (A), Cytosine (C), Guanine (G), and Thymine (T). With the assistance of hydrogen bonding, the reciprocal base pairing of Guanine to Cytosine and Adenine to Thymine are correlated. These hydrogen bonds are what keep together the two ends of the DNA helix between complementary nucleotides.
